Mount the Transmitter

For dimensional drawing information refer to Appendix A: Reference Data.

Electronics Housing

Provide 0.75 inches (19 mm) of clearance for units without an LCD display. Three inches of clearance is required for cover removal if a meter is installed.

Cover Installation

Always ensure a proper seal by installing the electronics housing cover so the o-ring is engaged. Use Rosemount O-rings.

The Rosemount 4500 is designed to be mounted directly to a process pipe or vessel using a standard sanitary fitting. The transmitter is available with either a 1.5 or 2-inch Tri-Clamp®connection or a fractional line fitting.

When installing the transmitter to the sanitary fitting it is important to use the proper sanitary clamp and gasket (user-supplied). Check the clamp and gasket specifications before installing. Refer to Table 2-2for a list of standard sanitary clamps, their respective maximum pressure ranges, and the recommended torque to be applied when mounting.
